The authors investigate a non-autonomous ratio-dependent predator-prey model with exploited terms. By using coincidence degree theory, they establish the existence of at least four positive periodic solutions for the above model. A related paper is \textit{S. Chakraborty, S. Pal} and \textit{N. Bairagi}, Nonlinear Anal., Real World Appl. 11, No.~3, 1862--1877 (2010; Zbl 1198.34077).
